next-stats-action: avoid pnpm EXDEV during stats installs (#90100) ## Summary - fix flaky `pnpm install` failures in the stats action caused by cross-device hardlinking (`ERR_PNPM_EXDEV`) - force `pnpm` to use `--package-import-method=copy` for installs run in temp repos - apply the same setting in both install paths used by the stats workflow x-ref: https://github.com/vercel/next.js/actions/runs/22110883672/job/63906643545
